OZONE GENERATION APPARATUS

To provide an ozone generation apparatus capable of efficiently providing ozone.SOLUTION: An ozone generation apparatus 1 includes: a fist structure 10 including a first electrode 14 and a first dielectric 12 that includes the first electrode therein and has a first surface 12a; and a second structure 20 including a second electrode 24 and a second dielectric 22 that includes the second electrode therein and has a second surface 22a. The first structure and the second structure are arranged such that the first surface of the first dielectric and the second surface of the second dielectric face each other. The first electrode includes an opposed surface 14a facing the second structure. The first structure includes a plurality of discharge-starting point structures 16 on a side closer to the second structure than the opposed surface, wherein discharge is induced on the discharge-starting point structure. When density D is the number per square centimeter of the plurality of the discharge-starting point structures and an interstructure distance H is a distance by the centimeter between the first surface and the second surface, 2≤D*H≤9 is satisfied.SELECTED DRAWING: Figure 1 【課題】オゾンを効率的に供給可能なオゾン発生装置を提供する。【解決手段】オゾン発生装置１は、第１電極１４と、第１電極を内部に備えるとともに第１面１２ａを備えた第１誘電体１２と、を備える第１構造体１０と、第２電極２４と、第２電極を内部に備えるとともに第２面２２ａを備えた第２誘電体２２と、を備える第２構造体２０と、を備える。第１誘電体の第１面と第２誘電体の第２面とが対向するように第１構造体と第２構造体とが配置されており、第１電極は、第２構造体と対向する対向面１４ａを備えており、第１構造体は、対向面よりも第２構造体側に、放電が誘起される複数の放電起点構造１６を備える。複数の放電起点構造の１平方センチメートル当たりの個数である密度Ｄと、第１面と第２面との間のセンチメートル単位の距離である構造体間距離Ｈと、が、２≦Ｄ＊Ｈ≦９を満足する。【選択図】図１
